Refactor knowledge base and models

[verovaleros]

Description

This PR introduces some important changes:

1. Each module was moved to its own file, with individual atomic logic.
2. The Knowledge base logic was moved to its own file to decouple from prioritizer and rf models
3. A new function _rebuild was added such that it can be called to rebuild the entire knowledge base from bin/aip
4. A new option to call the rebuild process was added to bin/aip
5. Logging was improved, making sure there are verbose and debug options, that are starting to be propagated through AIP to control the level of information.

closes #44
closes #47 (There is more work on logging to be done, but now, all prints are removed)

Type of change

• Breaking change (fix or feature that would cause existing functionality to not work as expected)

How Has This Been Tested?

Tested with multiple scenarios: existing, incomplete or empty knowledge base; run one model in the past; run all models in the past; run all models in the future; etc.
